Abstract:
Seamless Prediction of weather and climate is a crucial way to promote services and is characterized by multi-time scale forecasting, usually from sub-seasonal to decadal prediction (S2D), which is considered to fill the gaps between weather and climate, near-term and long-term climate prediction. Improving prediction skills for extreme weather and climate disasters will undoubtedly contribute to disaster risk reduction and the sustainable development of the monsoon regions. The latest FGOALS-f2 ensemble prediction system is a seamless prediction established in 2019—four fully coupled components of FGOALS-f2, including atmospheric, oceanic, land, and sea ice modules. The dynamic core of the atmospheric component is FV3, and the critical process of the physical processes in the atmospheric part of FGOALS-f2 is a resolved convection precipitation scheme. FGOALS-f2 prediction system achieved not only 30-year forecasts but also began operational prediction in 2020. Recently, the FGOALS-f2 outputs of the sub-seasonal to seasonal (S2S) prediction have been submitted to WWRP/WCRP S2S Phase 2 Project. The prediction products cover global and regional areas, such as ENSO, MJO, TC, Arctic Sea Ice, Tibet Plateau, and surrounding Asian monsoon regions. Some typical applications of the seamless system in the monsoon region will be introduced.
